A QR Code (it stands for "Quick Response") is a mobile phone readable barcode. In its simplest sense think "print based hypertext link" - simply encode a URL into the QR Code and then point a mobile phone (or other camera-enabled mobile) at it. If the device has had QR Code decoding software installed on it, it will fire up its browser and go straight to that URL.
Static QR Code: The actual destination website URL is placed directly into the QR code and can’t be modified.
Dynamic QR Code: A short URL is placed into the QR code which then transparently re-directs the user to the intended destination website URL, with the short URL redirection destination URL able to be changed after the QR code has been created.
